Ladd had the penultimate goal for the winning team. Hartnell had the penultimate goal. I suppose Kane had the penultimate winning goal if you're looking at the 4th goal for the Hawks in game 5, but that would be a weird record. Ok, I need to hit the dictionary again. But I think we get the gist of it. Kane's the youngest ever to net the GW goal that won the SC for his team.
